BRAKE-BAND-CONTROLLING DEVICE,

Application filer l ebrum'y 26, 1926. Serial No. 90,925.

My invention relates to hrake hand con.- trolling mean, and is more especially adapted to ii-midi means whereby the distance of? inoveineiu; of the brake hand away from i-he hralte drum is controiled so an to reduce the ainoiniii. of IHOVQHlOnl) of the brake hand necessary to hring ii; in contact wich the brake drum. My device is adapted to be attached lo most all of: the brakes in use, or peeially on automobiles,

in. the draivii'ig, Fi euro 1, is a side View of a h'rake, having my device uttached thereto, end Fifi. 2 is a view of my device iaken on the line 2, :2 0i Figure 1 wiii'h (he hralie hand and drum ()Iillilifiil. .ljn the drawings 1, 1 is the upper and iower portion of; the hrulze hands which are adnpted in he drawn, in any well known manner (not shown), in'lio coni'aci'; Wii'h the hrnhe drum 2. These 131': he hem is a, carried on a pin 5 and are arranged, when released from contact with. ii-he drum, to he moved away from the drum 2 by a spring i=3 At the hack or left of the drum as shown in i igure l, the spring tends to draw ihe hands much iertlun' a ay from the drum than is necessary and this requires additionel niovenien i), when the brake is being applied, o'i (he hralce hands toward the drum. To overcome i'lilS Tl: provide a hraclcet 6 which is hoited as shown to the brake support or hrackei; 7 hy bolls 8, 8. This bracket 6 is provided with :l'langes 9 extending ourr over the hra ke hand substantially parallel theren'iih. 'ihese flanges have openings or holes 10 therein Woich are threaded to receive adjustmei ii' screws 11. A lock nut 12 is provided so that when the :idjusiincnt screw is in its desired position to engage wiizh the hral re hands at the required distance away from the drum it can be locked in that position and held urge-inst movement until an other adjusinuml; isdesired. As will be seen the ends of adjustment screws contact with the brake hand, and. prevent the further movement oi. the hands away from the drum 2. From time to time as Wear on the brake i i iper means {or aiiixi chinesaid hrachel; adjacent the hrnlcel mils, and ad .a'nhie means carried at opposite ends If suid hracket io engage the hrake hands and conili'ol i'he distance of move- .nieniz ol same a ay from li-he hraho drum,
